摘要：
我们提出了HaptoFloater，这是一种利用不可感知颜色振动的低延迟空中视觉-触觉增强现实（VHAR）系统。当向空中图像的视觉信息添加触觉刺激时，用户不应感知到触觉与视觉信息之间的延迟。然而，传统的基于相机检测指尖定位的空中图像触觉呈现方法，会因图像处理和通信产生延迟。为缓解这一延迟，我们采用了颜色振动技术；当显示器以25赫兹或更高频率在两种不同颜色刺激之间交替时，人类无法感知到这种振动。在我们的系统中，我们将这种不可感知的颜色振动嵌入到由微镜阵列板形成的空中图像中，指尖设备上的光电二极管直接检测该颜色振动以提供触觉刺激。由此，我们的系统可在59.5毫秒内实现对空中图像上多种图案的触觉感知。此外，我们使用我们的VHAR系统和具有单一图案且响应速度更快的触觉执行器，评估了空中显示器上的视觉-触觉延迟容忍度。我们的用户研究结果表明，视觉-触觉延迟容忍度为110.6毫秒，这远大于使用多种触觉图案的系统所伴随的延迟。
英文摘要：
We propose HaptoFloater, a low-latency mid-air visuo-haptic augmented reality (VHAR) system that utilizes imperceptible color vibrations. When adding tactile stimuli to the visual information of a mid-air image, the user should not perceive the latency between the tactile and visual information. However, conventional tactile presentation methods for mid-air images, based on camera-detected fingertip positioning, introduce latency due to image processing and communication. To mitigate this latency, we use a color vibration technique; humans cannot perceive the vibration when the display alternates between two different color stimuli at a frequency of 25 Hz or higher. In our system, we embed this imperceptible color vibration into the mid-air image formed by a micromirror array plate, and a photodiode on the fingertip device directly detects this color vibration to provide tactile stimulation. Thus, our system allows for the tactile perception of multiple patterns on a mid-air image in 59.5 ms. In addition, we evaluate the visual-haptic delay tolerance on a mid-air display using our VHAR system and a tactile actuator with a single pattern and faster response time. The results of our user study indicate a visual-haptic delay tolerance of 110.6 ms, which is considerably larger than the latency associated with systems using multiple tactile patterns.
